ABSTRACT:
A dual biased magnetic transducer capable of sensing magnetically recorded data on a magnetic medium without any relative velocity between the transducer and the medium. The transducer includes a third DC bias field for aiding the DC field created by the data on the medium for substantially shifting the level in the AC carrier, thereby producing a computer compatible intelligible signal.
